Tone detector settings
The GSM gateway can automatically detect user defined tones transmitted by
GSM/UMTS for setting up outgoing calls to the GSM/UMTS networks. In general, they
are tones of a transferred number. For the purpose of such detection, the GSM
gateway automatically terminates the call and tries to set it up via another available
outgoing group (if defined in the LCR).

Sequence list – set the sequence of the tones to be detected.
Voice message detector settings
Minimum percent to match – set the match percentage range in which the voice
message is detected as identical with one of the voice messages recorded in the
section under index 30 - 37. The
